" To all. whom it may concern:

Be it known that I, FAUST' ZAnorNoNI, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Dumping Trucks, of which the following is a specification.'

The invention appertains to certain improvements in dumping vehicles, and'more particularly to the motor truck class'of such vehicles. i

The principal object of the invention is to provide fora mechanically refined construction and arrangement of dumping mechanisms for the bodies of vehicles of the type specified, and of a nature particularly adaptable for application to vehicles of light weight construction, whereby to facilitate the operation of the dumping bodies thereof' with the ease and rapidity comparable to the present ,known and larger trucks and vehicle dumping mechanisms whether actuated manually or'by a power means.

Another object of the invention is the provision of a truck of this character wherein the load carrying body is supported for tilting movements, the chassis of said body being constructed in a novel manner, so that, when the body is brought to rear end tilt 'ing position, it can rest upon inclined portions of the chassis at the rear end thereof, and thus relieve, to a certain extent, the weight of the load from theaxis of the tilting movement of said body.

Anotherobject of the invention is the provision of atruck of the character mentioned,

and one wherein the dumping body thereof,

comprises a transverse bracket extending when in tilting position, enables through gravity action, the dislodging and complete discharge of a load fromthe body, the body 'beingsupported in a novel manner and theraising and lowering thereof hein effected through the medium of a nove l means, which is manually controlled by the operator of the truck. A. further object of the invention is the provision of a truck of the type mentioned, and one which is comparatively sine-1e in construction, thoroughly reliable and efficient in its purpose and operation, and inex ensive to manufacture. With he foregoing and other objects in view, the invention, constituting divisional subject matter of my copending application 'filed May 23, 1921, and serially numbered 471709, resides in the certain noveland useful construction and arrangement of parts as will be hereinafter more fully described, set forth in the appended claims, and illusjtrated in the accompanying drawing, in

which l Figure 1 is a fragmentary side elevation,

partly in section, of a preferred embodiment thereof, are a pair of bearings 12' in which is journalled the opposite ends of a dumplng shaft ,13, carried in bearing brackets 1& depending from and at'opposite sides of the dumping body frame 15. The pivotal point of the body frame 15 or the journalling of the shaft 13 at or near the point as shown, provides for a major length of the dumping body frame to overlie the vehicle chassislO in a direction toward the forward end thereof, and for the rearwardly directed minor end portion of the bodyto ex- 'tend' outwardly from the rearward-1y" in clined end portion ll-of thesame.

The hoisting and lowering mechanism between and secured at theopposite side bars of the chassis 10, and this bracket con-- sists of a pair of upper and lower bars or plates 25 and 26, and an angularly bent brace bar 28 interposed between the bars or plates and connecting the lower bar or plate 26 at its opposite ends and having its medial portions engaging an intermediate portion ofthe .u'nder face of the upper bar '25. Ris ing from the opposite outer side of the chassis l0 andsecuredthereto as at 45,-are the oppositely angularly bent portions of a bar or plate 46, which is arranged to have its medial portion extending transversely of the chassis above and parallel to the bracket bars or plates 25 and 26. J ournalled shaft 29 being journalled in a bearing 47 and has keyed on the same, inwardly of the bearing 17 a bevelled pinion 31 arranged in mesh with a bevelled'gear 32, whlch is, in turn, keyed on a vertically disposed shaft 33- journalled at its opposite ends in the bracket bars or plates-25 and 46. Carried on the shaft 33, above the bevelled gear 31,

is aworm gear. 34}, arranged in mesh with the .worm wheel 35 keyed on a shaft 36 extending transversely of the chassis 10, and journalled at its opposite ends in the vertical portions of the bar or plate as. Keyed on the opposite ends of the shaft 36 are a pair of pinions 48 arranged in mesh with a complemental pair ofv curved rack bars 49, which are dependingly supported at their upper 'ends from a shaft 50, which, in turn, is journalled between the reinforcing and longitudinally extending bars or beams 23 and 24: secured on the under side of the body and forming the supporting frame thereof.

In the operation of this form of the invention, assuming thatthe body frame 15 is in its normally horizontal position on the chase sis 10 and loaded, turning movement of the hand crank 30, Will rotate the shaft 29, the

bevelled gear 31, the bevelled gear 32, they worm gear 34, the worm wheel 35, the shaft 36, and the pinions 48 carried by the latter, when the rack bars I8 will travel in an up ward direction raising the body 15 to dumping position.

In full dumping position, .as shown in Fig.1, the rear end portion of the body frame 15 will be supported on-the inclined end portion of the chassis 10, whereby to take a major portion of the load strain thereof off of the pivotal point of the body on the chassis. From this position, the lowering operation of the body frame 15 is accomp-lished by the manipulation of the hand crank 30, on the gearing of the hoisting and lowering mechanism in areverse direction of rotation, and this movementis facilitated by the weight of the major forward end portion of the body inward from its pivotal point on the chassislO. 1

By reason ofthesdisposition of the axis or pivotal-movement of the body, the force of gravity is exerted on the opposite ends of the body during its tilting movements in a 'manner to greatly facilitate themanual actuatlon of the dumping mechanism, whereby to minimize the pivotal exertion on the part of the operator during either direction of tilting movement of the body, and'it is obvious that the axis or pivotal point of the body may be located at any point on the.

modifications of the same may be resorted to without departing from the spirit of themvention, or of the scope of the claims appended hereto. 1

what is claimed, is I I.

1. A truck for the purpose set forth comprising achassis, a tiltingfbody supported 7 Having thus fully described the invention,

i so

thereon, a bearing bracket securedto and e tending transversely of the chassis, a trans versely extending inverted yoke-shaped support secured'tothe chassis and positioned over said bracket and p'r'ovidedwith openings, curved rack. bars pivotally'connected to said body and extending through said openings, .a shaft journalled in saidsupport and provided with a pair of p'inions engaging with said rack bars for shifting them, a worm wheel securedto the shaft and means supported by said bracket and meshing with said worm wheel for driving it, causing thereby the operation of said shaft. v
